If you're talking also about combos not perfectly landed, Mao landed a clean 3F+3T and a DG with -1 GOE 3F+3Lo in her 2008 Worlds FS, but I think that under the 6.0 system they would be both considered clean http://www.youtube.com/watch?v=8i_Z1uJnUeU
Gracie Gold at Salt Lake International Classics landed 3Lz+3T and 3F+1Lo+3S (the video should be in the IN archive)
Polina Shelepen last season landed many times 3Lz+3T and 3S+3T in her FS (just one example: http://www.youtube.com/watch?v=gcnQ-...OJTL7LLDvfzySw )
